Title: Improvements in or relating to annular sealing elements
Inventor: KLINGER-LOHR HUBERT
IPC: F16K5/06
Filed: 1963-04-01
Abstract: 966,833. Seals; pipe joints; valves. ISTAG A.G. SUHR/A.G. April 1, 1963, No. 12768/63. Headings F2B, F2G and F2V. A sealing ring, Fig. 2, comprises an annular packing 1 formed of a sealing strip of resilientlybonded, non-combustible fibres and radially compressed between metallic sheath ring members 2, 3 whereby only the two end faces of the packing provide sealing surfaces. As shown, one of the sealing surfaces is spherically concave. The fibres may be asbestos, glass or mineral wool and may be bonded by synthetic or natural rubber or by a resilient plastic material. They may be reinforced by abrasion-resistant inserts 5 such as nickel or aluminium foil or mesh. The sheath members 2, 3 may be in the form of single rings or one or, as shown, both of them may be formed of coiled metal bands which may be corrugated. The members may be provided with screw-threads as fastening means. In a method of making the sealing ring, the packing 1 prepared from a wound sealing strip is pressed into the space between the sheath members 2, 3. In another method, the sheath member 3 in the form of a steel tape is first wound on a mandrel, the individual windings being welded or cemented together. A sealing strip is then secured to the member 3 or to the mandrel and wound on to the member 3 by means of a roller exerting pressure radially inwardly, whereafter the sheath ring 2 is wound on to the sealing strip. A nickel wire mesh strip is fitted between the windings of the sealing strip. The spherical concave end surface of the packing 1 is produced by turning or grinding or by moulding with a ball-shaped member in the presence of heat. The plane end face of the packing 1 may protrude from the plane end faces of the sheath members 2, 3. The end face of the member 3 adjacent the spherical end face of the packing is bevelled inwardly. Fig. 4 shows a ball-and-socket type pipe joint in which the sealing ring 20 is fixed in a recess in the socket 18 and has its spherical surface co-operating with the movable ball member 17 which is urged towards the socket by a sleeve 21 screwed thereon. In another embodiment, Fig. 3, two sealing rings 1a are used to seal a ball valve 6 to the housing 7 of a tap and to a flanged conduit 8. The valve is rotatable by a pin 11 secured to a handle 8<SP>1</SP> and sealed to the housing by a stuffing-box 10, 12.

Title: Phosphor and method of preparation thereof
IPC: C09K11/84
Filed: 1966-03-23
Abstract: A phosphor material is characterized by the empirical formula M1(2-x)M11xO2Ch where M1 is at least one of La and Lu, M11 is one of Dy, Er, Eu, Ho, Nd, Pr, Sm, Tb and Tm, O is oxygen, Ch is at least one of S, Se and Te, and x is between 0.0002 and 0.2.  In preparation, preferably oxalates are coprecipitated from a nitrate solution of M1 and M11 with oxalic acid, converted to a mixed oxide by heating in air at 600 DEG  to 1300 DEG  C. for 0.2 to 4 hours, the mixed oxide then heated in H2Ch at 900 DEG  to 1300 DEG  C. for 0.2 to 2 hrs.  The phosphor may also be prepared by firing a mixture of oxalates in H2S, or a mixture of sulphates in H2, or a mixture of oxides in C2S, or a mixture of sulphides and oxides, or oxalates, or sulphates in N2 or H2, or a mixture of sulphates in H2S or C2S, or a substantially stoichiometric mixture of oxides and sulphides in a neutral or reducing atmosphere, in all cases at 900 DEG  to 1300 DEG C. for 0.2 to 2.0 hours.  Red emitting phosphors such as La1.90, Eu0.10, O2S and Lu1.98, Sm0.02, O2S and green phosphors such as La1.97Tb0.03O2S may be used in cathode-ray tubes.

Title: Improvements in or relating to machines for wrapping articles
IPC: B65B11/42
Filed: 1933-05-03
Abstract: 411,662. Wrapping- machines. BUREN, J. VAN, 750, Grand Street, Brooklyn, New York, U.S.A. May 3, 1933, No. 12928. [Class 94 (i).] Cakes of soap and like articles, which may have been enveloped in a preliminary wrapping of paper, are wrapped in transparent cellulosic material. The wrappers are fed between guides 52 on a table 51, a length being severed by blades 53, 54. A bar 80, supplied with solvent from a reservoir R by a wick 81, is mounted on a lever 83 and is depressed to apply the solvent to the wrapper. The articles are fed over a table 61 and between guides 74 by a horizontal plunger against a plate 115, and a plunger 116 descends to carry the article with the wrapper into a pocket P on a rotary carrier C, folding it about three sides and leaving upstanding edges E, D. At the same time plates 981 on the carrier form the first end tucks. The pockets are formed by spring-pressed side plates 96 and a base 99 mounted on rods 100 frictionally slidable in bores in the carrier. The plunger 116 ascends and the edge D is folded down by a roller 147. The roller is carried on a frame 146, Fig. 2, pivoted at 145 to a horizontally reciprocable frame 135 and is urged downwardly into contact with the wrapper by a spring 148. The roller is circumferentially grooved to minimize contact with the moistened surface of the flap E, the grooved areas being separated by longitudinal strips 165. During the folding operations, the roller is rotated by bevel gearing 150, 152 to effect a tight fold. After the flap D has been folded down, the carrier C rotates through 120‹, and the flap E is folded down by an arcuate stationary plate 170, which may be heated by a coil 171. The plate is mounted on sliding rods 167, springs 169 being interposed to ensure resilient action. Upon arrival at the position of the pocket P<1>, the packet is thrust into a guideway 172 by the action of a plate 105 on the rear end of the sliding rod 100. The sides 173 of the guideway form the van leading end tucks, and the lower broad flaps are folded up by the action of an inclined slot 176. Solvent is now applied to the under surface of the upper broad flaps by wicks carried by tubes 182 intermittently raised into contact with the flaps by belt-crank levers 813. A plate 190 turns about its pivot 196 and carries the packet between plates 199 which turn down the flaps to complete the packet.
Patent GB-760523-A (GB)
Title: Electro-optical apparatus
IPC: H04N7/18
Filed: 1954-05-04
Abstract: 760,523. Television. BOSCH, F. J. G. VAN DEN, and PINGEN, G. J. L. May 4, 1954, No. 12978/54. Class 40 (3). Electro-optical apparatus for viewing a specimen SP comprises a plurality of light sources A-G, at least three of which each produces a light spot which scans the specimen, the sources operating intermittently and in succession and the resulting images being formed on the photo-cathode of an electronmultiplier photo-tube or an electron camera tube SI, such as a super-iconoscope, the signals from which are applied to a cathode-ray viewing tube. The apparatus effectively views the specimen from a number of different directions producing an illusion of depth in the reproduced image. As illustrated, sources A, B, D, E and G scan the specimen and each comprises a cathode-ray tube ACRT controlled by suitable line and frame time bases to produce a television-type raster scan. Sources C and F do not scan the specimen and comprise ordinary filament lamps EL. Each source is associated with crossed polarizers AP, PP and a Kerr cell KC whereby the light may be extinguished by the application of a suitable voltage pulse a from a synchronized pulse source. The sequential switching of the sources may take place at dot line or frame frequency. In the case of operation at dot frequency it is stated that the scanning in successively operated sources is delayed so that each scanning spot appears at the same position. Thus with screen light sources as shown, the switching from one source to the next takes place after the first spot has moved through a distance equal to one seventh of its diameter and the start of the scan in the next cathode-ray tube is delayed throughout this interval. The direction of scanning of cathode-ray tubes, such as D and E, located above the specimens is reversed with respect to that of the tubes below. Where an electron camera tube is used this is scanned at a mulitple of the scanning rate of the light sources. In a modification, Fig. 2 (not shown), the polarizers and Kerr cells associated with the scanning light sources are dispensed with and the switching is effected by pulses applied to the cathode-ray tube guide. The light from the sources is preferably rendered monochromatic by filters MF. Reference is made to an arrangement in which nine monochromatic scanning light sources are used, four placed symmetrically at 90 degrees above the specimen and inclined at 45 degrees to the plane of the specimen, four placed similarly below, and the ninth placed as at A in Fig. 1 in line with the photo-tube or electron camera. At least four polarizing sources are also employed situated in the same plane or differing by only small angles, e.g. 5 degrees.

Title: Improvements in or relating to nuclear reactors
Inventor: BAUER STEFAN GEORGE
IPC: G21C7/26
Filed: 1958-04-25
Abstract: 916,324. Controlling reactors. ROLLSROYCE Ltd. April 27, 1959 [April 25, 1958], No. 13295/58. Class 39 (4). A nuclear reactor is controlled by varying the level of an absorbing or moderating liquid in tubes extending into the moderator. Fig. 1 shows a reactor with heavy water moderator in a tank 10. The tank contains tubes 21, open at the bottom, in which the water level is controlled by the pressure of the gas supplied through pipes 23. The gas pressure is controlled to keep the water level at a constant position in each tube. The tank 10 is connected to a dump tank 15 in which a high He pressure P 0  is maintained. This pressure is supplied to valves V 1  which pass on to valves V 2  a pressure P R  equivalent to the pressure head of a column of moderator of the desired length. A reference pressure P 4  is derived from a plane grid of tubes 38 below the reactor. P 4 -P R  is measured in V 2  and the result used to control the supply of gas from the dump tank to the tubes 21, so that the length of the moderator column is kept constant regardless of pressure variations or tilting of the reactor. Valves V 1  are controlled by a weight and a lever arm which may be adjusted to alter the pressure P R  and hence the moderator level. Each tube 21 may have its own control system.

IPC: C01D3/08
Abstract: 134,665. Bury, E., Ollander, 0., Smith, T., and Bainbridge, F. Dec. 3, 1918. Potassium chloride.-In the recovery of potassium salts from blast furnace slag, the addition of calcium chloride and the removal of the potassium chloride volatilized is effected while the slag is flowing from the furnace to the ladle. The caleium chloride to be added is introduced from a hopper 6 into the stream of molten slag as it flows from the furnace by conduit 2. Intimate mixing takes place as the slag falls down a cascade 3 into the chamber 4, from which the potassium chloride fume is drawn off by pipe 8 to the scrubber 10, where it comes into contact with water introduced through pipe 11. The resulting solution of potassium chloride is drawn off by pipe 12, whilst the treated slag, which is stated to be improved for the making of slag cements, flows away to the ladle by the conduit 5. An alternative cascade plant is described.
